Common Problem
At present, a brazing furnace or high-frequency induction brazing is used. The two welding processes are not perfect at the current stage and require a lot of application and verification. Relatively speaking, the current high-frequency induction brazing method is better, because the equipment investment cost is low, more flexible, and the later use cost is also high. But the versatility is not good, and the requirements for the product structure are relatively high. The equipment purchase cost and use cost of the brazing furnace are very high, and it is difficult to support it if the batch is not enough.
To sum up, at this stage, induction brazing technology may be a preferable welding method.
